Problems solved by technology

[0003] And for the ultra-long tape machine (length is greater than 4 kilometers) of more than 4 drive motors, its drive motor can carry out head-to-tail configuration (the present invention is 5 motors, 4 heads, 1 tail), traditional high-voltage frequency conversion The motor and computer synchronization technology can ensure the power balance and speed synchronization between the head drive points, but the tail motor does not have a good follow-up solution. If the synchronization control is not good, it will cause problems during the start and stop stages, especially when starting with load. Causes the impact of mechanical and electrical systems, produces overlapping belts, makes the dynamic tension wave of the belt conveyor harmful to the belt and mechanical equipment, and shortens the service life of the conveyor

Embodiment Construction

[0019] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the multi-drive belt conveyor synchronization system provided by the present invention includes five motors, belt conveyors, 2 sets of control devices (programmable logic controllers), 5 sets of high-voltage frequency converters and related networks.

[0021] In the present invention, two sets of control devices are used to carry out synchronous real-time calculations, and the operating speed and current of five motors are monitored in real time. The control program of the control devices is divided into 2 parts:

[0022] Among the four motors at the head, the first motor 16 and the second motor 18 are rigidly connected, the third motor 20 and the fourth motor 22 are rigidly connected,...

Abstract

The invention relates to a synchronizing system of a multi-transmission rubber belt conveyor and belongs to the technical field of metallurgical mines. The synchronizing system has the advantages that the computer synchronizing control technology is improved, four motors at the head drive a rubber belt conveyor in a balanced manner while the current and frequency of the drive motor at the tail are synchronously calculated and adjusted in real time to allow the output power and the operation speed of all the motors at the head and at the tail to be balanced so as to guarantee stable operation of the rubber belt conveyor, impact on machinery and an electric system during fast starting / fast shutdown is lowered, belt overlapping is avoided, possible harm, caused by rubber belt conveyor dynamic tension waves, to a rubber belt and mechanical equipment is restrained effectively, the service life of the rubber belt conveyor is prolonged, and safety and reliability of a conveying system are increased.

Description

technical field [0001] The invention relates to the technical field of metallurgy and mining, in particular to a multi-drive belt conveyor synchronization system. Background technique [0002] For long tape machines driven by 4 or less motors (the length of the tape machine is greater than 2 kilometers), the motors are all arranged at the head of the tape machine, and high-voltage frequency converters and computer synchronization technology are generally used. [0003] And for the ultra-long tape machine (length is greater than 4 kilometers) of more than 4 drive motors, its drive motor can carry out head-to-tail configuration (the present invention is 5 motors, 4 heads, 1 tail), traditional high-voltage frequency conversion The motor and computer synchronization technology can ensure the power balance and speed synchronization between the head drive points, but the tail motor does not have a good follow-up solution. If the synchronization control is not good, it will cause p...
